Definition
Noun: 1. A purified liquid produced by condensation from a vapor during distilling; the product of distilling. This is the core scientific and industrial meaning. It refers to the liquid that results from the process of distillation, where a mixture is heated to create vapor and then cooled to condense it back into a liquid, separating it from impurities or other components.
Examples of Usage

Advanced Usage

- Figurative Use: While less common, "distillate" can be used metaphorically to mean the most essential, pure, or concentrated part of an idea or experience.
